First you need a continuous integration server (which will run the tests and builds). I recommend Jenkins. Then with a few settings on Jenkins you can start running JUnit. Then so as to not rock the boat too much, start by just writing tests for all your own code. If that goes over ok, add tests for critical functions, such as data operations or things like that. You can print out coverage reports pretty easily with Emma. http://jenkins-ci.org/ http://jenkins-ci.org/ http://emma.sourceforge.net/ http://emma.sourceforge.net/
